WASTE-PIPE VALVE FOR BATH-TUIBS.

To all whom it may concern.

Be it knownthat I, VVILLIAM G. NEWTON, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in WVaste-PipeValves for Bath-Tubs; and I do hereby detute part of this application,and represent,

Fig. 2 a vertical sectional view of a waste pipe shownas applied to a tub having feet. Fig. 3 a sectional view on the line(4-4) of Fig. 2. Fig. & a sectional view on the line 0d of Fig. 2.

This invention relates to an improvement in valves for Waste pipes forbath tubs, and particularly to waste pipes the valves of which open by ahandle at the top of the tub, either outside the tub in case of solidbase tubs, or extending through the flange of the tub in case of tubsprovidedwith feet.

The object of the invention is to provide a construction which permitsof ready attachment especially to a solid base tub but equally adaptedto tubs provided with feet,

and the invention consists in the construetion hereinafter described andparticularly recited in the claim.

In Fig. 1 of the drawings, I have shown the device applied to a solidbase tub, that is, in which the waste opens through one of the walls ofthe tub as distinguished from opening through the bottom of the tub, as

shown in Fig. 2. In either case, however, I

employ a valve-casing 2 adapted to be coupled with the tub eitherthrough an opening 3 in one end of the tub as shown in Fig. 1 of thedrawings, or in connection with a cou pling member 4:.opening throughthe bottom of the tub. This valve casing 2 includes a circular valveseat 5 opening into the tub and closed by a segmental valve 6. Thisvalve has inwardly projecting sockets 7 and 8 adapted respectively tocontain springs 9 and 10 and to receive studs 11 and 12 pro-Specification of Letters Patent.

jecting into them from a yoke 13 attached to the lower end of anupwardly extending arm 14 guided by a sleeve 28 formed integral with thethreaded coupling 29. To the upper end of the arm 14 a valve stem 15 isattached. The upper end 16 of this valve stem is flattened on one sideto be engaged by a coupling-member 17 having a D-shaped hole 18 intowhich the upper end 16 ofthe stem extends and so as to be firmly engagedthereby, yet free to move vertically to compensate for tubs of differentheight. This coupling-member 17 is rigidly connected Patented Apr.6,1915.

with the handle-stem 19 provided at its upper end with a handle 20 bywhich it may outside the tub above the upper edge thereof as shown inFig. 1 of the drawings, or may extend up through the flange 21 of thetub as shown in Fig. 2 of the drawings. The valve stem is inclosed bytubing 22 having a cap 23 which connects with the usual overflow 2 1 andnear the top of the tub. Preferably the casing 2 will be provided withan outlet opening 25 in line'with the connection to the waste at thebottom of the tub and closed by. a plug 26 so that the connection withthe tub may be conveniently cleaned. By turning the handle 20 the valvestem 15 is turned so as to move the valve to-open or close the passageto the waste at the bottom of the tub, the springs 8 tending to holdthevalve upon its seat and provide for any inequalities as to the internalface thereof.

In Fig. 4 of the drawings the valve is shown in its closed position inwhich the outlet in the bottom of the tub is closed. The valve seat orinner wall of the valveis provided with a stop rib 27 against the endsof which the edges of the valve 5 will strike so as to limit themovement-of the valve.

When the valve is turned to the open posi-.

tion water in the tub may freely flow through the valve, and when turnednearly to its open position and the plug 26 removed, access may be hadto the coupling" with the tub so that it can be conveniently cleaned.

This arrangement of valve is easily applied to tubs having solid bases,or to tubs seat, a segmental valve in said casing hearing on said seat,said valve formed with two inwardly projecting sockets, a yoke providedwith two studs entering said sockets,

said yoke formed with an upwardly project-- ing arm, a guide sleevethrough which said arm extends, a valve stem connected with said arm, anoperating handle provided With a handle stem, and means for coupling thehandle stem with the valve stem said cou- 'WILLIAM G. NEWTON.
